What else is out there?

No matter what you write, research is important. But beyond knowing background about the people, places and things of your story, it’s good to be able to know what has already been written about your subject.
Just how many histories of crocheting already exist? What else has been written about sparkling vampires or robotic lawmen?
One place that can help with that research is the American Library Association’s Booklist magazine and website.
